These 2 disks are OS Disks of IMAGES (and no Virtual Machines) I created a month ago. This is why they did not appear in "Virtual Machines -> Disks". I will delete these images, which i don't use anymore.

As you have already use BreakLease.ps1 which did not delete your VHD, it is possible that your VHD is still listed in Virtual Image -> disks. Would you please check it?

So when you delete the VM, the VM configuration is deleted however the OS disk is still left. OS and Data disks are listed in Virtual Image -> disks and if a OS disk which is not associated with any VM or a Data disk which is not attached to any
OS disk, such disks are orphan disk as they are not attached to any VM or disk. You can delete the disk directly from portal. After that you can go ahead and delete the disk directly at your Azure Blob Storage.

Would u please give another try and see if that helps you or you still have problem?
